regcache: rbtree: use the regmap scoped lock guard

Browse Source 
Convert the open-coded map->lock()/map->unlock() pair in rbtree_show()
to guard(regmap)(). The locked region spans the whole function body up
to the single return, so a function-scope guard drops the manual
unlock with no functional change.
